This will be part 2 of the LED cube build (part 1 was 2 weeks ago). I hope to have some PCBs I sent away for and be able to move to the component assembly phase of this project. The LED soldering & construction will hopefully be done. Please come by and see what's happening. Don't worry if you didn't make it to part 1 -- you can easily come in and pick up where we are currently at.
Update 2/8/13: 18:00
I have been giving some more thought on the cube building project. We have 11 people signed up and I am considering breaking the project into 3 major chunks - YOU pick the chunk you want to work on (or any combination, as YOU see fit). I am just thinking that having all 11 of use doing each step may not be the best way to do things and people may not be interested in the soldering part, for example. If we do break up into three teams, these efforts will happen simultaneously. If we don't, they will happen serially. So, here goes:
Part A) Kit parts inventory, sorting, LED testing, 8 LED "plane" assembly. Includes basic component handling, soldering, etc. You will learn/do parts ID, testing, soldering.
Part B) Breadboard assembly. Includes circuit board reading, breadboard parts configuration, soldering, testing, etc. You will learn/do parts ID, breadboards, wiring, component handling, testing (power supplies, meters, etc.)
Part C) Software - bring-up and display algorithms. Get the development environment up and running, find test s/w, find display algorithms, get them up & running and ready for the final bring-up & test. You will learn/do about the "Process" S/W environment for the Ardunio chip, the compiler, downloading, C programming, etc.
Part D) Final bring-up, test, fun - ALL of us will do this!
I think having a team lead (or two) for each chunk makes some sense. This would be a person who knows how to get each of these tasks going and help others who know less (I am not, for example, a breadboard expert).
If you have expertise at one of these efforts and would like to lead, please let me know and we'll do it. I was thinking I would take Part A and am hoping for someone to lead Part B & C (I have expertise and can help on C but am weak on B).
I want to again stress two things: 1) I will not be leading any kind of "class" - I will be there to answer any questions I can (as I am sure others will too) but my goal is to make progress on the project and help all of you get what you want out of the meetup. 2) This "plan" is just a suggestion and is not concrete. I am open to any ideas and modifications that make things go best for all involved. I will however not let things devolve into chaos... I look forward to meeting each of you and haveing a lot of fun!!
8x8x8 LED Cube building project
This is one of the coolest projects I've seen recently. The cube doesn't look like much...until you watch the video. It's fully animated!
Join Scott at the Sacramento Hacker Lab while he builds one. You can work on one of your own, check his out or lend a hand if you wish. The Hackerlab has graciously opened up to allow this meetup to be at their location in downtown Sac. This is a great opportunity to see the lab (I have not seen it myself, yet). There should be great exposure to their facilities, other like-minded people, etc. Now that the meetup is at the lab instead of my house, I can lift the restricted RSVP count too! If you do come and want to help and can bring a soldering iron and basic tools, please do. Until we figure out what's at the lab, I have been ashed to be somewhat self-sufficient.
Here is what I am hoping for for this event:
- see the Hacker lab and become familiar with its organizers & facilities.
- Start work on the 8x8x8 cube project. From what I understand, there is a lot of labor involved.
- get any and all help I can in assembly. I hope this both inspires and teaches others to follow along. If you'd like to solder, etc., you can be a co-builder.
- Once I get ready to "fire it up", connect to it with a PC and start the software evaluation and programming process (I have not researched this much yet). I will hope for help if the cube does not come up correctly (hardware experts, oscilloscopes, etc.)
What you can expect:
- Exposure to the Hacker's Lab and it people. This is a great way to see what's going on in the industry and maybe find work or look for good people.
See the parts for the kit - how complex is it. I will gladly supply a photocopy of the parts list for those who want to purchase parts apart from a kit.
- An opportunity to learn to solder and assemble if you don't know how
- An opportunity to see how to do the final "bring-up" and initial testing (when we get that far - it may be at a subsequent meetup)
- An opportunity to see the software that runs the cube and how it works and how to modify it. I am a software engineer so my sleeves will be rolled high for this part of the process. I love to share my expertise :)
- I will not be leading any formal class or instruction - everything will be VERY informal.
Here is an instructable showing the entire project...
Here is video of the cube in action...
If you're resourceful, you can collect the parts from several sources for $50-60 or you can buy a complete kit here...
If you'd like to come by and work on your own kit, see mine, help, etc., etc., by all means please do.
Please email Scott at [masked] for more details or call at[masked]-8608.
I am sure I missed some things so please email me with questions. I will keep updating this posting as I think of new stuff to add. I hope to see you there!
Please carpool, if you can.
